ZR-3930D type ambient air particle sampler Introduction
The ZR-3930D ambient air particle sampler (multi-channel type) is a six-channel homologous parallel sampler that simultaneously collects TSP, PM10 and PM2.5 in the atmosphere. The special shunt structure allows the particles containing TSP grain size to be evenly distributed into the six sampling channels according to isotropic, so as to achieve homologous parallel sampling of particle classification.
